The average approval of $584,047 sits well above the median of $240,000, so a small number of large deals is pulling the mean up. The median is the better guide to what a typical borrower here actually gets. Only 10.3 percent of approvals run on real estate terms, so SBA credit here is mostly working capital and equipment rather than property acquisition.

Of the 302 loans that have reached a final outcome, 7.0 percent were charged off. This is computed only over resolved loans, because a loan still running has not yet succeeded or failed and counting it either way would be wrong.

Compare against the national and state SBA charge-off rates, computed the same way over resolved loans only.

Coverage
What this page does not hold.
Every item below could be filled with a plausible figure. None of them is. On a page a lender may read, a number that cannot be traced is worse than an absence, so the absences are named.
- Flood zone record counts are not held. The flood coverage export has not landed, so no count is shown rather than an estimated one.
- Traffic counts resolve in the platform, not in this dataset, so no AADT figure is printed here.
- Zoning is in build. Parcel level zoning is not published on this page.
